Microcontrollers are not at all difficult as they sound. Mostly students at MCS are hesitant to include microcontrollers in their projects as they are neither taught in any course nor there have been any workshop or seminar on this topic as far as I know. But really they are as simple as writing a basic program in C++. A microcontroller operates by changing the voltages of its output pins. Output pins typically take on two discrete voltages (usually 0 and 5 volts). Each output pin reflects the value of some bit in the microcontroller's memory. When the bit is set to 1, the pin goes to 5 volts, and when the bit is set to 0, the pin goes to 0 volts. Some applications they are used for are data acquisition, logical voltage supply, control system, interfacing and so on.
Common microcontrollers that are easily available in Rawalpindi College road, Pakistan are 8051, 8052 etc and these are the ones you would probably like to use and create an additional charm in your project. And they are not expensive as you might think, they cost about Rs. 50-70 only. Google 8051 or 8052 and you would come across so many resources about them. Some useful readings and resources are mentioned below.
